wheels 13 and the gear-wheels C and C in conneetionwith thefriction-disks will be held securely in mesh as will be understood fromFigs. 1 and 2 of the drawings.

At their outer edges'at their inner sides the disks D and D are providedwith ribs D having coincident annular grooves D, forming a ball-race inwhich the. balls D operate, relieving friction between the parts andpermitting the disks D and D to move inde-. Pendently.

By the described construction it will be noticed that as thefriction-disks are turned motion will be transmitted to their respectivewheels through their counter-shafts, as before described. I

For driving the friction-disks we provide the opposite pnliey-shafts Fand F, which extend parallel to the planes of the friction disks and aregeared together at one end by gear-wheels G, G, g, and g, the gears G,G,

g, and g meshing", as shown in Figs. 1 and 4,

- and being inclosed in an oil-tight case G and the shaft G connectedwith the gear 9, be. ing the bower-shaft, which in practice is suitablyconnected with an engine or other form of motor.

By the described construction it will be noticed the shafts F and F willbe caused to rotate in opposite directions, so that the friction-pullesthereon and presently described, bearing on the friction-disks on theopposite sides of the same, will operate to turn their respective disksin the same direction.

The shafts F and F are made in sections united by universal 'oints at fand f (see Fig. 1) to permit t e pulley-shafts to be moved toward andfrom the friction-disks in order to set the friction-pulleys into andout of frictional engagement with their disks without throwing the gearsbetween the pulley-shafts and drive-shaft out of mesh.

The main sections of the shafts F and F are. journaled in bearings ineccentrics H and H, inounted in suitable strap-frames h and it, (seeFigs. 3 and 6,) the eccentrics being connected by links I (see Fig. 1)with levers J, pivoted at J to the frame at the opposite cnds'thereof,and the opposite levers J 'being connected by a rod J so the levers maybe operated jointly to set the shaftsllfl and F toward or from thedisks.-

The pulley-shafts F and F are juuvided; with longitudinal keyways F andfrictioni pulleys K k K k are keyed on the shafts F engagement with thefriction-disks to the position shown in Fig. 1 their correspondingpulleys k and is will be moved into engagement with the friction-disks,and vice versa, or the friction-pulleys may be shifted to such positionthat all the. friction-pulleys will be clear of operative engagementwith the friction-disks, being in such arrangement in a neutralposition, as will be understood by those skilled in the art, and byshifting the pulleys toward and from the center of the friction-disksthe speed may be varied. The frietion pulleys are constructed alike andhave rawhide or other similar rims 1 and hubs 2, which latter aregrooved circumferentially at 3 to receive yokes 4 on the shifter frameL. i This shifter-frame extends around the group of friction-pulleys andis supplied with a yoke 4 for each of said pulleys and is provided atone end with a rack 5, meshed by a pinion M on a suitable shaft, so theshifterframe may be moved longitudinally to set, the pulleys inengagement with the frictiondisks and in proper relation thereto, as maybe desired, for the purpose of varying the speed, reversing the motion,or stopping the gear. I

The shifter-frame L is preferably made in. sections telescopicallyconnected at L so the front pulleys'k and k may be moved to a limitedextent independent of the rear pul leys 1i and K. In the constructionshown the side bars of the shifter-frame are made with rods Z, headed atl and fitting in tubes P, which are slidable in bearings l on the 'mainframe, springs 1 operating between the bearings l and the end of theshifter-frame connected with the pulleys K K, as best shown inFig. 1.front pulleys may be moved into and out of action without changing theposition of the two back pulleys, but at the same time by moving thefront pulleys forward out of engagement with the disks D and D the headsZ will drag the tubes Z through the bearings Z and bring the backpulleys forward into.
